It doesn't necessarily mean it's a collab. It could be an affiliate link, which means she gets a tiny tiny %. But I see she doesn't have #AF written on it. Who knows, maybe she was being sound sharing the link coz it's on sale, and also gave her an opportunity to say she PAID FOR IT (well done hun, like the majority of the population have to pay for their bits, don't come looking for recognition) but I highly doubt St Terrie would share any link unless get a few cents for it somewhere! Or maybe if they see enough people buying from the link they will eventually give her a collab coz they'll know its worth their while then
ETA sure its hard to know what they are and aren't declaring! The industry needs to be way more regulated. Tax man is missing out on a fortune with these beggars I'd say!
